Subject [jira] [Commented] (CASSANDRA-3219) Nodes started at the same time end up with the same token
Date Fri, 16 Sep 2011 18:56:09 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13106701#comment-13106701

Vijay commented on CASSANDRA-3219:
----------------------------------

Can we also have some thing like "equal split" which will try to split the token ranges into
perfect halfs? this will work well for bootstrapping ring of sizes = 2^n

> Since autoboostrap is defaulted to on when you start a cluster at once (http://screenr.com/5G6)
you can end up with nodes being assigned the same token.
